Nice build and great sounding vibe, no need to buy one from JHS when you can build it yourself to your own liking. I had a tiny issue with a broken trace I found when measuring continuity on the PCBs. The trace between the 1n5817 and 47uf wasn’t working but when I made a small bridge from the...

I’ve acquired 2n5088s for an Electrovibe Mini I’m going to build. I noticed that most measure around 718 HFE but some are above 800, some are around 616 and one is 477. This was with a cheap measuring device. Does the HFE and leakage matter in this circuit? EDIT: Measured them again with my...

I should receive the Souldrive PCB tomorrow or Friday and got some 1n916 diodes for the clipping section, should be similar to 1n4148 probably. I also want to try some higher mV diodes like BA282/482 or MA856. Might open up the pedal a bit more so I’ll give those a try and see how they respond...

Can someone help me with how to create a veroboard design from the schematic below? This is the trimpot PCB for an Ilitch backplate denoiser coil that I'd like to create on veroboard. On the left the BPNCS (back plate noise coil) is shown which has a resistance of about 335-360 ohm.

I’m trying to better understand why biasing sometimes works and sometimes doesn’t work. I have a practical question about the Sandspur / Sunflower PCBs. I’m trying to use 2n1308 NPN germaniums in the Sandspur and noticed that the collector voltage of Q2 can’t get below around 5,5V. Bias and...

I’m building a number of fuzz faces with the Sunflower and Sandspur PCBs and the Solaris and Epsilon AION PCBs. Also the Tactical Fuzz. The clean control of the Sunflower/Sandspur is 50k (I make it externally controllable) and the AION ones use B 250k pots. Both seem to work fine but I was...

I'm using 2 Ilitch noise coil solutions, one with a backplate and another one routed underneath the pickguard. This noise coil has a resistance of around 350k (for standard) which works for standard output single coils. Ilitch includes a small PCB with 2 trimpots and a few SMD caps to dial in...

I own an original Maxon SD-9 and I’m interested to experiment with a number of PCBs which are similar. This thread is to share insights and mod experiences. I’m going to build an AION Meteor (Mods from the SD9M (mids) and a clipping switch) and the PPCB Samurai (based on Way Huge Geisha Drive)...

I build a Clandestine preamp yesterday and its quite a nice pedal. I got around 23v on R101 and I set the bias to around 13.9v (just right of center of the trimpot) which is about 60%. The pedal operates well and the 3 EQ presets work nicely. I noticed something very peculiar which I've...

I recently build quite some pedals using Robert’s superb PCBs. Here’s 10 of them. ;) Left to right: - Abider - Fordoble - Mystery Meat - Duocast Left to right: - Cattle Driver - General Tso’s - Paragon Mini - Modus Operandi - Cobbler - Special overdrive I will detail some of them below...

I just build a Fordoble boost and overdrive and the Arche boost side is too bright IMO. I discussed this with @HamishR and he suggested using a 2n2 cap in parallel across the 51k which is just before the output which he also mentioned in a forum thread. I tried some higher cap values and IMO...

Are the envelope filters by PPCB or others comparable to the EHX Nano Q-Tron pedal? Looking to build something comparable with a volume control as well.

I just build the cobbler and noticed that the top range of the treble control is extremely piercing. I checked some demos on YouTube and my build is sounding comparably except for the treble knob. Since there’s no schematic yet I tried tracing the components around the B1M treble control: -...

I've noticed that Musikding has a very limited stock of colored 125B enclosures. Are there any other suppliers in the EU?

There have been multiple discussions on the forum about the PackRat, Fat Rat and (Jam Pedals) Rattler. I've build a legacy AION Helios pcb in the past but want to try out some other things so I ordered a Muroidea PCB. (The Triad Distortion wasn't in stock in the EU here) I noticed that Jam...

I’ve juist build a Lithium from AION Fx which is an EHX Small clone with a mix control and a depth pot instead of the 2 way switch. I didn’t get any chorus at first which turned out to be a broken bias trimpot. In the description it says this about the depth control: Depth knob The original...

I've build a AION Vector some time ago and use it as the last pedal before the Flint and amp. I use this pedal only as a slap delay with no repeats and a low delaytime. This sounds different then a slap delay on a Timeline. If I drive the input with comp and/or boost pedals (Tchula - Tsos -...

I've build the Corduroy fuzz for the 2nd time and after a succesfull build with a working brightness pot (wasn't working in the first build) I found the pedal too dark and replaced the 25k bright(ness) pot with a 50k pot. This was tedious and hard to remove and somehow the 50k pot doesn't seem...

I need your help with something: I’ve played the Corduroy some more and found it too dark so I removed the 25kB pot and replaced it with a 50kB. It’s brighter now but the brightness pot doesn’t do anything anymore! This was one of the issues when I first build this circuit, this is my second...

I got a new Corduroy PCB and received new MMBFJ201s. I also build a small JFET tester this time so I can measure Idss and Vp Of the J201. So the MMBFJ201 I used before in the failed build have the following Idss and Vp values: - Idss 0,67mA, 0,76mA and 0,78mA - Vp -0,81V, -0,86V and -0,88V The...
